Protect your cables, protect your revenue
Greenlight® is Synaptec’s unique HV cable resilience solution, enabling the highest levels of cable network availability and health.
Greenlight leverages passive and permanent sensing to provide early warnings of damage and failure in cable assets, reducing the need for costly and high-risk manual inspection and scheduled maintenance, and avoiding unnecessary outages.
The Greenlight solution delivers high-fidelity measurements from every cable joint and termination to a real-time analysis platform, where operators can observe and react to abnormal activity on their network in advance of critical failures.

Greenlight provides early warning of failures
Key Benefits
- Early warning – Supports operators in early cable fault or damage identification, enabling early intervention, avoiding costly outages and unscheduled maintenance.
- Cost-effective – A low cost / high return solution for monitoring health, damage, and degradation in power cables and their joints and terminations, regardless of their number or distance.
- Prevents failures – Models cable and accessory health and behaviour to guide proactive maintenance far in advance of failures.
- No maintenance – Uses passive sensors which operate over distances of up to 60 km from the substation and do not require control power, maintenance, or recalibration.
- Easily deployed – Small, non-invasive, and easy to retrofit. Works with any HV cable – underground or subsea (i.e. solid-bonded and cross-bonded cable architectures).
The industry challenge
Cable failures continue to cause significant financial and operational strain for power grid and offshore wind operators. A single event can cost over £80M in lost revenue, along with substantial outage time and repair costs.
Cable failures also account for 83% of insurance claims in the offshore wind industry, so early warning and intervention is critical to avoiding these unplanned costs, and reducing outages.
Crucially, 57% of cable downtime is now known to be due to joint and termination failures rather than the cable itself. However, effective monitoring of those remote locations is not cost-effective with conventional techniques. A comprehensive approach to passive monitoring of the full cable network is required.
Challenges for offshore wind operators
- Cable failures remain the biggest unpredictable risk in offshore wind operation
- Most happen in joints and terminations, unseen by conventional monitoring techniques
- A cable termination failure on an export cable can cost over £1M per day in lost revenue, for a mid-sized wind farm
- DTS, DAS, ROV, and PD are all late or unreliable indicators of damage and failure
Challenges for power grid operators
- Cables are vital assets, but joints are remote or inaccessible to monitor
- Outage cost and reputation damage is significant
- Conventional condition monitoring is expensive, inefficient, and insufficient to spot damage, and is a lagging indication of insulation failure
Our solution
Greenlight improves availability and reduces outages by monitoring at all joints and terminations. It provides operators with permanent and continuous monitoring of these critical locations, giving early warning of damage and abnormal behaviour, reducing maintenance costs and manual effort. Greenlight’s sensing technology operates without any control power, data networks or ongoing maintenance. Install once, and Greenlight delivers early warnings for decades.
